The field experiment was carried out during the summer season of 2021-2022 to study response different weed management practices on growth and yield black gram. Cyperus sp., Phyllanthus niruri, Trianthema portulacastrum, Amaranthus viridis were dominant weeds. It observed that besides free treatment lowest count, dry weight weeds (3.66 g m-2), index (2.73%) as well highest control efficiency (6...

in order to study the effect of pyridate, bentazon and imazethapyr herbicides on chickpea growth, nodulation and biological nitrogen fixation, a greenhouse experiment was conducted at ferdowsi university of mashhad in 2010. experimental type was completely randomized design with four replications. treatments included pyridate, bentazon and imazethapyr herbicides application in 1200, 720 and 75 ...

Background: The presence of weeds in cowpea reduced the yield to tune 60-82% depending on weed flora and density. critical period competition was 20-25 DAS. Therefore it is essential control effectively harness maximum potential crop. To manage also important determine efficacy pre post-emergence herbicides. Sequential application herbicides a short duration crop not only increases cost product...

The bioassay conducted in controlled conditions was used to investigate the sensitivity of selected crops (maize, sunflower, wheat, sugar beet, oilseed rape and mustard) imazethapyr carryover. dešendence whole protein content test plants roots measured regard different concentrations soil. rates were established at 240, 120, 60, 30, 15, 7.5, 3.75 1.875 mg A.I. kg-1 soil (ppbw). After sowing, gr...

this experiment was arranged as a strip-plot on the base of a completely randomized block design with three replications to study the effect of tillage (whether in day or night or in day by light-proof cover) and application of reduced dosage of imazethapyr and trifluralin on weed control, yield and yield components of chickpea. main plots consisted of tillage methods and subplots consisted of ...

Imazethapyr is an herbicide that used in a variety of crops worldwide, including soybean and corn. The aim the present study was to evaluate biomarkers responses adult Leptodactylus latinasus exposed formulation Pivot® H (10.59% imazethapyr) laboratory at concentrations under conditions simulate two potential field exposure scenarios: immersion runoff (Scenario 1: 10 mg/L) direct droplets emitt...

Context Yield losses in lentil (Lens culinaris ssp. Medik.) caused by weeds are estimated at 20–80%. In the absence of effective broad-spectrum herbicides, menace weed has emerged as a serious yield constraint lentil. Aims Identification tolerance to two post-emergence imazethapyr and metribuzin. Methods 221 accessions were screened experimental research station International Center for Agricul...

Red rice and rice belong to the same genus and species. Both are selfpollinated plants, but some outcrossing has been documented. Due to outcrossing, there are chances of resistant gene transfer from herbicide-resistant rice to red rice, which may increase the weediness of red rice. In 2000 simultaneous flowering was observed between Clearfield® CL2551 and red rice at the Rice Research and Exte...

A reduced herbicide rate with hand-weeding (HW) can act as a safer and sustainable approach for weed control. field study was conducted at CSIR-IHBT, Palampur, India during 2018 2019 to analyze the efficacy of herbicides in combination manual weeding on control yield wild marigold (Tagetes minuta L). The experiment laid 12 treatments, consisting two dosages prescribed rates (R) pendimethalin, i...

This study demonstrates that corn can be partially safened by BAS-145138 against sulfonyl­ urea and imidazolinone herbicides. The corn seeds were impregnated with BAS-145138 by soaking the seeds for 6 h in solutions o f the safener. BAS-145138 had no effect on corn growth. However, corn shoot and root growth in length, fresh weight, and dry weight was partially protected by BAS-145138 from the ...
